--------------------------------------
Created SPARK-18683. But I don't have time to work on it now. I can help review
PRs if someone picks it up.
> Standalone REST API throttling?
> -------------------------------
>
> Key: SPARK-13287
> URL: https://issues.apache.org/jira/browse/SPARK-13287
> Project: Spark
> Issue Type: Bug
> Components: Web UI
> Affects Versions: 1.6.0
> Reporter: Rares Vernica
> Priority: Minor
>
> I am using the REST API provided by Spark Standalone mode to check on jobs.
> It turns out that if I don't pause between requests the server will redirect
> me to the server homepage instead of offering the requested information.
> Here is a simple test to prove this:
> {code:JavaScript}
> $ curl --silent
> http://localhost:8080/api/v1/applications/app-20160211003526-0037/jobs | head
> -2 ; curl --silent
> http://localhost:8080/api/v1/applications/app-20160211003526-0037/jobs | head
> -2
> [ {
> "jobId" : 0,
> <!DOCTYPE html><html>
> <head>
> {code}
> I am requesting the same information about one application twice using
> {{curl}}. I print the first two lines from each response. The requests are
> made immediately one after another. The first two lines are from the first
> request, the last two lines are from the second request. Again, the request
> URLs are identical. The response from the second request is identical with
> the homepage you get from http://localhost:8080/
> If I insert a {{sleep 1}} between the two {{curl}} commands, both work fine.
> For smaller time outs, like {{sleep .8}} it does not work correctly.
> I am not sure if this is intentional or a bug.
